Fusion processes , like combining two deuterons to form a He nucleus are impossible at ordinary temperatures and pressure . The reasons for this can be traced to the fact

A

nuclear forces have short range

B

nuclei are positively charged

C

the original nuclei must be completely ionised before fusion can take place

D

the original nuclei must break up before combining with each other .

This question has statement I and statement II . of the four choices given after the statements choose the one that best describes the two statement Statement-I Eclipsed and staggered form of n-butane can be easily isolated at room temperature. statement-II Energy difference between these two forms are not very high and at normal temperature pressure energy required for conversion staggered to eclipsed form is available from the atmosphere.

In has been estimated that the total energy radiated by the sun is 3.8xx10^26 J per second. The source of energy of stars is a thermonuclear reaction called nuclear fusion. Fusion reactions are not controlled. It is presumed that the energy of stars is due to two processes called proton-proton cycle and carbon nitrogen cycle. Fusion cannot take place at ordinary temperature. This, hydrogen bomb uses a small fission bomb, which on explosion causes the temperature to rise very high about 10^7 K. We have yet to see how a hydrogen bomb can be used for peaceful life-sustaining purpose. Energy released in the process of fusion is due to mass defect. It is also called Q-value. Q =Deltamc^2 , Deltam= mass defect Answer the following questions based on above passage: Fusion reaction takes place at about:

For H_(2) gas, a=0.024L^(2)*atm*mol^(-2), b=0.026L*mol^(-1) and for CH_(4) gas: a=2.28L^(2)*atm*mol^(-2) , b=0.042L*mol^(-1) . (i) At ordinary temperature and pressure, which one of the two gases will behave more like an ideal gas? (ii) Which one of the two gases has a larger molecular size?

At ordinary temperature, why can CO_(2) but not O_(2) gas be liquefied by applying pressure? Give reason.

At ordinary temperature and pressure, solid NH_(4)Cl dissolves in water to form NH_(4)^(+)(aq) and Cl^(-)(aq) ions. The process is endothermic. Indicate the signs (+ or -) of DeltaS_(sys),DeltaS_("surr"),DeltaH and DeltaG .

Under certain circumstances , a nucleus can decay by emitting a particle more massive than an alpha -particle. Consider the following decay processes. (a) ._88^223Ra to ._82^209Pb + ._6^14C , (b) ._88^223Ra to ._86^219 Rn + ._2^4He Calculate the Q-values for these two decays and determine that both are energetically possible. m(._88^223Ra) =223.01850 u, m(._82^209Pb) =208.98107 u, m(._86^219Rn) = 219.00948 u, m(._6^14C) = 14.00324 u and m(._2^4He) =4.00260 u

The binding energies of deuterium (._1H^2) and helium (._2He^4) per nucleon are 1.1 MeV and 7.0 MeV respectively . When a helium nucleus (._2He^4) is formed by fusion of two deuterium nuclei then how much energy will be evolved ?
